i think first of all swing voters want to sigh some sense of energy and optimism and particularly from a challenger competence and i think romney who i always thought romney would clear that bar. i always thought romney is someone americans could imagine sitting behind the desk in an oval office, and in the last few weeks, there is actually some reason to doubt that, the 47 percent tape, his stiffness and i think last night you saw as mark said people who followed him and have seen this before, last night you saw the romney i think americans would say you know i can imagine that guy sitting behind the oval office desk and really important to see what polls look like not just today but really four or five days from now, we know the history of debates, is that for all of the attention we give them, they rarely, rarely dictate an election, i mean the only one you can really argue that did was george w. bush and alore in 2000, even gerald ford a story people like to tell, ford fell more behind before the debate that doesn't mean the debates couldn't be a decider in this election, of course
